To all whom it may concern.' i

Be it known that I, JOSEPH C. GEFRING, citizen of the United States,residing at Pittsburgh, in they county of Alleghen u andv State ofPennsylvania, have invente certain-new and useful Improvements in Gas-Burners, of which the following is a specii ication.

This invention relates to gas burners and comprehendsthe production of agas burner wherein improved means is .provided for the mixing andcombustion of the-heating One ofthe objects of, the invention is .theconstruction of a sim le as burnerl having a gas superheating c am er inconnection with an air and gas mixin chamber so that the gas to beconsume 4 superheated and then-thoroughly mixed wlth the-air beforebeing converted into heat.

Another object vof the invention .is the construction of a gas burnerhaving a gas superheating chamber .arranged around a,l gas supply pipeand connected to a miningy chamber in such amanner that 4gas enteringthe superheating chamber from the supply pipe will be superheated so asto enter the 1 mixing chamber under pressure and in such a way as tointimately mix with air dra-wn in by said gas escaping from the super.`heating chamber.

. With the above and other objects in view vthe invention consists incertain combinations, constructions and a-rrangements-of parts, clearlydescribed in the followlng accompanying drawings, inwhich,

Figure 1 is a detail vertical sectional view showing one part of theimproved burner, Fig. 2 is a horizontal sectional view showing theconstruction of both halves of the burner, each half being like theother, Fig.

3 is a horizontal sectional View of a singlel illustrating the preferredform of themvention l denotes a gas burner, which is,

will rst be provided with mediately disposed discharge;

tubes 4 which project outwardly, said tubes bem formed lntegral withsaid burner;

T e horizontal partition 2 is connected with a vertical partition 5, theupper end of which projects above the horizontal partitical'partition 8,which is ofconsideraole less length than the partition or wall 5 ytowhich is screw threaded the gas supply- `and is spaced inwardly thereofby said art'ition 8 termipipe 10. The outer or intermediate vertif calpartition 5 is provided with minor discharge tubes or hollow-outletmembers 11,v

the bores of which are ared outwardly, and

'which are disposed within the plane of the discharge tubes, 4` butabove the lower sides of .said tubes or hollow members. It will` thus be'seen that a fluid expansion chamber is formed which is substantially'formed withl a central inverted U-shaped i partition, which extends to apoint above said discharge tubes or outlet members 11.

The mixing chamber is surrounded by a wall or. shell 12, which is-spaced apart from the intermediate wall 5 so as to -leave a channel .13through which air'can ow into the mixing chamber 3 and escape with thegas issuing from the minor discharge tubes 11, the bores of which areflared outwardly, and which are disposed within the plane of thedischarge tubes 4, but above the lower sides of said tubes.`

From the above arrangement it is to be noted that the Vdischargeconduits 4 are integrally formed vupon both the expansion vchamber 14andV the shell 12, and that the outlet members 11 .are integrally formedupon. said chamber at central and diametrically-opposite points andproject concentrically Aor between the walls of said conduits,

but terminate centrally of theair, channel 13, so that ythe escapingproducts of combustion may intimately mix withthe inrushihg air at thecorner. between the channel 13 and conduits 4.-

When the burner has been supplied with gas and the same ignited the top6 and the walls ofthe discharge tubes will be heated to a hightemperature. The vertical wall andthe top 6 and the bottom spacingpartition 7, with the inner partition 8 inclose a space whichconstitutesa superheating chamber 14. As the gas leaves the top of the supply pipe10 it will enter the superheating chamberV 14, striking against theheated top 6, and escape under pressure through the minor or gasdischarge tubes 11 into the upper part of the mixing chamber 3, andthence directly out through the gas and air discharge tubes 4. As thegas leaves the gas discharge tubes 11 it will be spread outwardly so asto enter the chamber 3 Vin a spray and intimately mix with the air,which will be drawn by the outflowin up through the entrance 13 into themlxing chamber 3 and out with the gas through the discharge pipes .4,which constitutel the burner tubes properj It will be noted that the gasdischarge tubes do not project across the entrance 13 but only half wayacross and that they are adapted to spray gas into the chamber 3 and thedischarge tubes 4 so that the gas will evenly enter said tubes, in-

stead of striking against one side or wall of same. iA part of the gasstriking the top wall 6 will be deliected downward so as to enter thelower part of the chamber 14,

thus being hea-ted by the lower part of the vertical walls of thischamber. The entrance 13 for the inilowing' air surrounds '40 the entirewall or partition 5 so that an abundance of air can enter the chamber 3.

Should it be desired to connect two supply pipes with the superheatingchambers a dividing wall or partition 15 is arranged between the supplypipes, as shown in Fig. 2. In Figs. 3 and 4 is illustrated a modifiedform of the improved burner, wherein 16 denotes an annular outer wall,which is provided with burner or discharge tubes 17,

ve being shown.` Within the outer wall\ 16 a wall 18 is disposed, beingprovided with gas discharge tubes 19 adapted to discharge gasinto thetubes 17 andthe space between the-partitions or walls 16 and 18. Withinthe wall 18 a partition or wall 20 .is disposed, being spaced apart fromthe wall 18 by a horizontal partition 21, in a manner like that of theconstruction Shown in Figs. 1

' and 2. The partition 18 projects above the plied with gas through thesu ly connected' with said chamber.

top of the outer wall or partition 16 to inclose ja superheatingchamber, like that shown in Fig.- 1, and thischamber is supl ipe 22 isorm of -to the tubes 24 and the wall 25 by a horizontal partition orwall 27. The structure 26 is divided by a central partition 28 into twocompartments and supply pipes 29 are connected to each of thesecompartments or chambers. From the sides of the box like structure 26gas discharge tubes 30 project so as to spray gas into the chamber 25and the tubes 24.

As gas leaves the upper ends of the pipes 29, which are located belowthe tubes 30 it will lstrike against the upper part or top of thechamber formed by the structure 26, be i deiected downwardly at a highertemperature, so as to strike in part the bottom of the structure 26, andthen escape through the tube 30, into the air -mixing chamber 25 andthence out throu h the tubes 24.

The outlet or ischarge tubes 4 are referably deflected at an upwardangle o thev wall 12, so that thesames esca ing from saidtubes will beinclined upwar ly of said wall 12. By this arrangement the ow of airthrough the mouth 13 will be stimulated, asa greater draft is therebydeveloped.

Having described my invention, I claim and desire to secure ,by LettersPatent 1. A burner comprising a relatively-large f iuid expansionchamber, a shell spaced around said chamber to form an air channeltherewith, hollow members communicating: with said chamber, conduitsformed integrally upon said chamber and shell to dischar e the fluidescaping from said hollow mem ers, said hollow members being disposedconcentrically of said conduits and terminating short of the mouththereof, and in) iuid inlet member connected to said cham- 2. In aburner comprising a relativelylarge duid-expansion chamber and an inlverted U-shaped partition .disposed in and spaced from the walls of saidchamber, the combination of a shell spaced around said chamber to forman air-conduit therewith, hollow members communicating` with saidchamber at .points below the top of' said U- shaped partltion, conduitsformed integrally upon said chamber and shell to discharge ,the Huidescaping from saidL hollow members, said hollow members disposedsubstantially coneentrically of said last-named conduits and beinglocated vbetween said chamber and shell, and a fluid inlet memberyconnected' to the base of said U-'shaped partition.

3. A burner comprising a relatively-large fluid expansion chamber, an.vinverted U- shaped partition, disposed in and spaced from .the4 wallsof said chamber, a shell spaced around said chamber to form anairchannel therewith, fluid' discharging con- 10 duits formed integrallyupon ,said chamber and shell, hollow imembers in line with saidvconduits and communicating with' said In testimony whereof I ailix mysigna- 15 ture, in presence of two Witnesses.
